two walls with an intermediate filling of asphaltum, or equivalentsubstances, have been constructed; also, double walls have been bracedtogether by means of horizontal strips and ties. Neither of theabove-named constructions, when used alone, is suitable for the purposeherein stated.

My invention, which consists in strengthening the Walls of vaults, andof effectually preventing leakage through the same, will now be readilyunderstood by referring to the aecompanying drawings, on 'which- Figurel represents a longitudinal section of my improved vault, and Fig. 2 asection through the line .fr fr thereof.

In vaults now existing it is only necessary to secure ties or anchors inthe walls thereof, and to face the said walls with a non-absorbentmaterial and inner wall, securing the whole together by the meanshereinbefore described.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-
